I mean send this in the console
M558 P1 C"^zprobe.in" H5 F120 T6000
G31 P500 X-26.0 Y-9.0 Z1.85And then try your homing.
Done, with the same result, the probe get triggered in the air.
Though I'm starting to wonder if it's something wrong with the IR probe itself.
I have to admit that you may be right. I have in total 3 of the ir-probes here. Two for my corexy build and the one in my CR10.
I replaced the one at my CR10 now with a other one. That seems not brand new any more, but it seems to work now. :?
But it is a bit to early for me to blame the bl-touch. I will play a bit more with the new one before I will confirm that the new one is working.And I will put the suspicious probe into the corexy for some tests.

Can you explain the homeall.g to me, please?
I'm fully confused now. I removed the "M98" so source the homez.g from the homeall.g. So it looks like that now:; homeall.g ; called to home all axes ; ; generated by RepRapFirmware Configuration Tool v2.1.8 on Sun May 10 2020 08:05:32 GMT+0200 (Central European Summer Time) G91 ; relative positioning G1 H2 Z5 F6000 ; lift Z relative to current position G1 H1 X-315 Y-315 F1800 ; move quickly to X and Y axis endstops and stop there (first pass) G1 H2 X5 Y5 F6000 ; go back a few mm G1 H1 X-315 Y-315 F360 ; move slowly to X and Y axis endstops once more (second pass) ;M98 P"0:/sys/homez.g"And you know what? The printer homes Z after it homed X and Y. WTF? I added a "beep" into the homez.g to test whether it get executed and not. And the printer beeped when I executed "G28" right after it homed X and Y.
So I think that the homez.g is executed whether I execute it or not.
Is that the expected behavior? -

Do you mean your "IR probe" is a BLTouch? This would not be an IR probe and is configurated differently.

Ahhhh.. no.. it is a IR-Probe! Not a BL-Touch, I replaces the BL-Touch with the IR-Probe.. sorry for the confusion. Forget the BL-Touch please..... My bad.
-
@Chriss ok - this would be the easist solution
-
@Chriss if you run homeall and the Z is homed unexpectedly: do you have any special files lying around in the sys or macros folder, which could produce this behavior (tool changing, override,...)? To find the reason, you should delete every files and lines which are not needed. (backup all first)
-
Hmmm... maybe but I do not see it, to be honest. I downloaded the content from the sdcard and grepped a bit in the files. The only files I found, which contain "G30" are:
macros/00_Z-Level:G30 P0 X20 Y155 Z-99999; probe near a leadscrew, half way along Y axis macros/00_Z-Level:G30 P1 X250 Y155 Z-99999 S2 ; probe near a leadscrew and calibrate 2 motors sys/bed.g:G30 P0 X20 Y155 Z-99999; probe near a leadscrew, half way along Y axis sys/bed.g:G30 P1 X250 Y155 Z-99999 S2 ; probe near a leadscrew and calibrate 2 motors Binary file sys/Duet2CombinedFirmware.bin matches sys/homez.g:G30 sys/homez.g:;G30 ; home Z by probing the bed sys/homez.g:;G30I fully understand your approach but I do not see any unexpected file. Or a file which may have it's bits in the cake.
I'm still very confused that the IR probe, which caused all the problems in the CR10, works very, very well in the corexy. :?

@Chriss I can explain my approach: you say when you run homeall, your Z is homed. But homeall doesn't contain any Z movement (only Z5), so there must be anything which makes the Z movement to trigger the signal. So I thought, something automatic like a tool change (tfree, tpost), heating up or something other could trigger the Z movement.
Looking at your files, bed.g could be triggered somehow.
Other possibility: if you run homeall and the X and Y are already in their endstop positions, is there something specific so the IR probe triggers immediately? (is the position of the IR probe outside your bed, e.g.? => could be the case, as X is 26 and Y 9 mm off the nozzle. To try you could position X and Y somewhere in the middle of the bed before calling homeall) And if IR triggers if it is outside the bed, it may be that the probe must be inverted with a ! in the M558 C command and maybe reduce sensitivity value G31 P value.

So I think that the homez.g is executed whether I execute it or not.
Is that the expected behavior?That's pretty peculiar.
Can you add an M400 before the M98 to call the homez? That should ensure it's finished all the previous X Y homing moves before moving on.
-
Indeed, it is very peculiar. Well, I needed a break, to I used the weekend do work on my fun car, that was bit more promising.
I tested this morning 8-10 times with "G28" and all axes got homed. And this is the homeall.g:
; homeall.g ; called to home all axes ; ; generated by RepRapFirmware Configuration Tool v2.1.8 on Sun May 10 2020 08:05:32 GMT+0200 (Central European Summer Time) G91 ; relative positioning G1 H2 Z5 F6000 ; lift Z relative to current position G1 H1 X-315 Y-315 F1800 ; move quickly to X and Y axis endstops and stop there (first pass) G1 H2 X5 Y5 F6000 ; go back a few mm G1 H1 X-315 Y-315 F360 ; move slowly to X and Y axis endstops once more (second pass) M400 ;M98 P"0:/sys/homez.g"Yes, Z got homed and yes, the beep from the homez.g changed every time I changed it. So there can be no other file involved.
I do not know why but the trigger up in the air went completely away. :? All of my test this morning where successful. Do not ask my why, the only change from last week was a very, very long power cycle.
But it is very odd to see the homing of Z but you know that you do not execute it from homeall.g. :?
Anyway, my main problem, the trigger in the air, is magically gone now. I'm not sure if I want to touch that again or not, it is working for now.
-
Actually I think this is totally normal. Homeall is homing all axis. It completed the homeall.g and the z axis was still unhomed, so it executes home z.
